ОО 0 1 0-1 Question 5 1 pts You're working with a discrete-time signal x[k]that has 2029 samples. You'll use the FFT algorithm to compute samples of X(12) To do this, you'll pad the signal with zeros so the overall length of the padded signal is well-suited for the FFT algorithm. For the choices below, which padded signal length would be the best choice? (Note: The factorization of each number is also provided). Padded length: 2041 = 13. 157 Padded...
